I can not apply patches to the git repository until the recent git issues are sorted, so I am attaching the patch to this email so that you can apply it locally if you like. I will push this up once our git repository is back in working order.

I don't think this is the intended behavior! The problem, it seems, is that when :tangle is not present, the (or ...) in the code below always evaluates to true. #+begin_src emacs-lisp (unless (or (cdr (assoc :tangle (nth 2 (org-babel-get-src-block-info target-file) (setq target-file (read-from-minibuffer "Tangle to: " (buffer-file-name) #+end_src

Tangling of single source blocks is a really nice feature now! Regards, Andreas

There was a conflict between the narrowing to a single code block caused by the prefix argument, and the code which searches for replacements to noweb elements. I've just pushed up a fix so noweb elements should now expand as normal. > > (2) I am asked for a filename.

Under Gnome, I'm using this at the beginning of a sh source block: echo -e "#! /bin/bash\n/usr/bin/gksudo -p -m Password" > /tmp/gksudo-stdout chmod +x /tmp/gksudo-stdout SUDO_ASKPASS="/tmp/gksudo-stdout" sudo -A -s Sylvain.

Thanks for the hint! Shouldn't this be mentioned in the manual (14.4)? I have two questions/issues about this: (1) Can I get noweb-references to be expanded by this? Or how would I tangle one block with noweb references expanded? (2) I am asked for a filename. But the header argument :tangle somefile is overruling my input, which is un-expected. Regards, Andreas
